Hi! After creating a Clay sheet with company data, can Clay automatically update the Primary Market Category field in HubSpot, or do I need to set up an explicit update action?
You need to set up an explicit update action. Clay doesn't automatically update HubSpot fields - you must configure a "Update object with HubSpot" action to push data from your Clay sheet back to HubSpot.
This action allows you to update any HubSpot object, including company records and their specific fields like Primary Market Category. You'll need to map your Clay data to the corresponding HubSpot field through the update action setup.
